概括
抵抗训练 (RT) 影响认知障碍的老年人血液动力学和身体表现. 即使是一组 (1SET) 和三组 (3SET) 显示好处,特别是对于那些严重损伤的人来说.
科学领域:
- 老年学是一门学科.
- 运动生理学 运动生理学
- 神经学 神经学
背景情况:
- 了解阻力训练 (RT) 对血液动力学和身体表现的影响对于认知障碍的老年人至关重要.
- 不同的抵抗训练量 (一组与三组) 对这一群体的影响仍未得到充分研究.
研究的目的:
- 分析一组 (1SET) 和三组 (3SET) 阻力训练后血液动力学和身体性能参数的急性和时间变化.
- 将这些影响与不同程度的认知障碍 (轻度,中度,严重) 进行比较.
主要方法:
- 三十九名年长的成年人 (80±9岁) 与不同程度的认知障碍 (轻度,中度,严重) 参与.
- 参与者随机执行了两种10次重复的方案 (1SET和3SET),分隔一周.
- 测量包括静缩血压 (SBP),静缩血压 (DBP),心率 (HR),药球投 (MBT),五次重复的坐立 (STS) 和手握强度 (HGS) 干预前后 (立即和72小时).
主要成果:
- 在所有认知群体中,对于大多数参数,1SET和3SET之间没有发现显著差异.
- 严重认知障碍 (SEV) 组显示SBP和HR急性增加,3SET后STS时间减少.
- 在72小时内,所有组都显示SBP降低. 在SEV组中,STS时间 (3SET后) 和HGS时间 (两种协议后) 均有所改善. 轻度 (MILD) 组显示SBP降低,而SEV改善了HGS (1SET) 和STS (3SET).
结论:
- 单重和多重阻力训练都会诱导急性血液动力学变化,在72小时内趋向于降低SBP.
- 患有更严重认知障碍的个体随着时间的推移,在身体表现方面表现出更大的适应性反应.
- 耐力训练,即使是单个组,也可以改善认知能力下降的老年人的身体功能和力量.

Exercise and Muscle Performance
1.3K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Cognitive Development During Adulthood
49
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Exercise and Cardiac Output
901
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...

Exercise and Cardiovascular Response
721
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
